Publication number: 20140326803Abstract: A water gun clearing apparatus, particularly for application in self-serve car wash units, for use in clearing standing water from hoses, pipes and the water gun as well as preventing residual water moisture from building-up within the water gun. The water gun clearing apparatus comprises an air regulation system connectable to a source of pressurized air, and a timer. The air regulation system comprises a first air line branch configured to provide a continuous supply of pressurized air at a first flow rate, and a second air line branch configured to provide a supply of pressurized air at a second flow rate. Following use of the water gun by a user, the timer activates and provides pressurized air to the water gun at the second flow rate for a pre-determined time period in order to clear residual water from the water line and water gun.Type: ApplicationFiled: May 3, 2013Publication date: November 6, 2014Inventor: Jinjing QUI

Patent number: 8851397Abstract: Rotary bell cup atomizing apparatus is provided having a rotatable bell cup driven by a motor shaft dimensioned so as to provide an annular gap between the outer, rear surface of the cup and the shaft extending an effective distance axially adjacent the shaft. Solvent channels extend within the assembly circumventing the gap and discharge into the gap. During cleaning of the atomizer, solvent passes partially through the paint nozzle and partially through the solvent channels impinging directly upon the shaft, then migrating over the outer surface of the cup. The inner and outer surfaces of the bell cup and the motor shaft are simultaneously cleaned. A replaceable sleeve placed inside the cup adjacent the front surface thereof absorbs the force of paint impinging thereon. The cup may have at least one balancing indentation immediately adjacent the sleeve.Type: GrantFiled: November 14, 2013Date of Patent: October 7, 2014Assignee: EFC Systems, Inc.Inventors: Gunnar van der Steur, Joseph Cichocki

Publication number: 20140252121Abstract: A system, in certain embodiments, includes a spray device including a first liquid passage configured to flow a first liquid in a generally downstream direction toward a spray tip. The spray device also includes a second liquid passage configured to flow a second liquid in a generally upstream direction such that the second liquid impinges upon the first liquid at an outlet to the second liquid passage. The upstream direction is substantially opposite from the downstream direction.Type: ApplicationFiled: May 26, 2014Publication date: September 11, 2014Applicant: Finishing Brands Holdings Inc.Inventor: Bradley P.

Publication number: 20140239090Abstract: In the present invention, a cylinder chamber is provided in a main injector body having a nozzle that injects fuel. In the cylinder chamber, a command piston for driving a needle that opens and closes the nozzle is reciprocably received. A cleaning liquid supply pathway for supplying cleaning liquid and a cleaning liquid discharge pathway for discharging cleaning liquid are connected to the cylinder chamber. As a result, adhesive accretions in the cylinder chamber of the main injector body are discharged out of the cylinder chamber together with the cleaning liquid, and therefore it is possible to prevent a negative effect resulting from the adhesive accretions without using an additive or the like.Type: ApplicationFiled: July 22, 2011Publication date: August 28, 2014Inventors: Wataru Minami, Shouji Yamaguchi, Yasushi Arai, Kouji Tahara
